Warner Bros has released a new trailer for Lego Batman: Legacy of the Dark Knight, showcasing the new Mayhem Collection DLC.
This DLC is mainly focused on The Joker and Harley Quinn, introducing them as playable characters with their own story mission. Both have their own gadgets and skills, with the focus being a breakout from Arkham Asylum itself. There’s also the new Mayhem Mode, which will task players with causing as much chaos as possible in a time limit across Gotham City by smashing vehicles and completing challenges, all whilst being chased by Batman and having to fight against ARGUS agents and even Task Force X.
Rounding out the release is the Sinister Pack, which adds themed outfits for the main roster, a vehicle and some Batcave items. You can see all the additions below, with the original source material in brackets:
